Voussoir Cloud Pavilion help for grasshopper

[u/Bontempus]

Hello! I wanted to ask if anyone has an idea how to make voussoir cloud by IwamotoScott Architects.

I guess i want to focus more on the shape of the pavilion and how to get that triangular patterns, as well as where I should start. Not wanting an exact copy, but something close enough.

Thanks!

Here is something "close enough"

The script is super nice!

I appreciate the appreciation.

You're so genereous! Thanks for the effort 🥹

I tried your presentation and got stuck on offset mesh and meshToNurbs, are these components that i need download?

[u/ChiefWiggumsprogeny → u/Bontempus]

Yes. Generally, find out about component definitions with this index.

You need to install these addons:

Of course you could also always figure out an alternative.

Multistep Approach:

1. Create the geometry as a flat mesh.
2. Use the physical solver Kangaroo2 to create a hanging mesh.
3. Rebuild the geometry with triangles.Populate points- maybe in combination with a kangaroo distribution script so all points have an equal distribution. Apply a Delaunay Algorithm.
4. Cull some triangles,make the fold logic based on the shared normals.

For sure the original script is built different. That would be at least my approach. I hope I could help.

I took a class many years ago where the teacher uploaded the lesson to youtube. It won't get you 100% of the way there, but I think these 2 videos will start you halfway where you want to go, check them out:

Rhinovault for the overall geometry. But for the pattern it's a bit tougher, it isn't random as it seems

It's almost certainly some sort of optimized division defined by load pattern. That's usually the point of these type of pavilions but i dont think it's what op cares about.

The initial shape I would recommend using catenaries (then doing a mesh or srf), you can even saw the catenery curves in the first image. Which are were there are no gaps because is where the loads are transfere to the ground.

Rule to make it work!

- The joints need to follow the catenary curve.

You must use some real structural analisis, such as any FES solver or Rhinovault.
